15Five MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to 15Five and the rest of your systems. It gives your agent 64 15Five actions (41 reads, 20 writes and 3 that wait for a confirmation) and holds the 15Five credential itself, so the agent never does. It paces 15Five's limits and records every call.

Set up

Connect 15Five in three steps.

01
Add actionlake to Claude.
Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.

Bearer token. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key.

Top actions

The 15Five API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 20 of 15Five's 20 action names are shared with at least one other connector, so an agent learns them once.

Governance for 15Five

Destructive actions wait for a yes.

3 15Five actions are destructive. These are all of them:

Delete vacationfifteenfive.vacations.delete
Delete check-infifteenfive.checkins.delete
Delete group typefifteenfive.group_types.delete

A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

dofifteenfive.vacations.deleteconfirm_policy: human

Delete vacation?

Illustrative. Scoped to 15Five only, capped at 2,000 upstream calls, every write confirmed, and the destructive ones approved by a named person.

Cost

What 15Five costs on actionlake.

Every 15Five action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call 15Five refused with 401, 403, 429 or a 5xx are free. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Questions

The 15Five MCP server, answered.

Is there a 15Five MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 64 15Five actions across group types, users, groups and objectives, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by 15Five.

What do I need to connect 15Five?

15Five API key. The free call account { op: "connections.requirements", service: "fifteenfive" } lists exactly what to paste.

Can an AI agent delete or change things in 15Five?

Only if its key allows it, and only with an explicit confirmation. 3 15Five actions are destructive, including delete vacation, delete check-in and delete group type. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my 15Five API limit?

actionlake paces every call to the limits in the 15Five service file: 5 calls a second per connection. Repeated reads are answered from cache (41 15Five actions can be), which never reaches 15Five.

What does a 15Five action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (64 15Five actions page). Cache hits, searches, dry runs and calls 15Five refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which 15Five API does it cover?

The 15Five Public API 1.0 (OpenAPI 3.0.0) at my.15five.com. It is built from 15Five's documentation as read on 23 October 2026. 64 actions in 26 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my 15Five data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your 15Five credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
